SUSPENDING ELECTRIC-LIGHTLAMPS.

SPECIFICATION forming part of Letters Patent No. 896,897, ated January29, 1889. Application filed January 26, 1888. Serial No. 262,035. (Nomodel.)

To aZZ whom, it may concern.-

Be it known that l, AUGUST SIEGltIs'l, a citizen of the United States ofAmerica, residing at llullalo, in the county of Erie and State of NewYork, have devised new and useful Means for Suspending I111cctric LightLamps, a specification whereof is as follows.

The object oi my device is to secure the electric-light lamp suspeluh-nlin such a manner that the swinging to and fro and the tip ping over inhigh winds, liable to interrupt the electric current, is renderedimpossible, and at the same time to have free access and ready means forraising and lowering suchlamps. This object is attained by mechanism andthe arrangement of a series of cables illustrated in the accompanyingdrawings, in which Figure I is a view showing two poles and end or fixedpoints, between which. and from one to another cables are drawn. The topor uppermost of these cables is stationary and used similarly as a cableis used for floating a boat across a river. Dotted lines show positionof lamp and cables when lowered. Fig. II is a horizontal section of suchcords or cables as drawn from one pole to another in such horizontalposition. Fig. III is a front elevation of one of the poles, showing thearrangement of cables descending from cross arms downward through a yokeand to wind lass. IV is a sectional view of the frame work forming thebasket carrying the lamp suspended from a carriage traveling on theuppermost or stationary cable. Fig. V is a cross-section of Fig. IV, andFig. TI is a cross section of the carriage or basket and its details.

Similar letters and figures refer to similar parts.

From windlass A from the middle part of drum, which part is in diameterseveral times larger than the outer parts, two cables or cords runupward and pass through yoke B, then spreading out reach the upper arm.Passing over pulley 1 they assume their course across. Ilalf-way acrossthe cables meet the basket C. Passing under pulleys 2, journaled inclaws provided on the upper end of uprights D, they again run upward andwind over pulleys 3, being pendent from carriage E, traveling onstationary cable F, stretched i from point to point on top of the poles.Going downward again, they pass under pulley 4, also jourualed in clawson upper end of u' )rights I), and from there first passing through yoke(it over pulley 5, they reach the upper arm of the opposite pole.\Vijnding over pulley (3 they go downward to 7, and, passing under 7,they start on their return across. Passing again through yoke G overpulleys 8, again meet the basket 0, to which they are made fast onpoints 0 c c 0. Up to these points cables actually form one section.However, if desired, they need not be cut, but may be continued, yetthey must be fastened nevertheless, and the basket thereby preventedfrom shifting on such cables and at such points. Returning farther thecables meet pulley," 9, and, passing over same, go downward againthrough yoke B and to Windlass A to parts of the drum having dian'ietersmaller than the part from which they started. The respective ends ofthese cables must be attached to the drum in such i'nanner that wheneverthe shaft is turned in the direction of the arrow at the crank, Fig. I,the starting ends, attached to the large drum, must deal out, while thereturning ends, attached to the small drums, are to take in.

The Windlass is provided with dog an d ratchets, and the dog is thrownoff whenever lamp is lowered, which is done by allowing drum to turn inthe direction of the said arrow. The lamp will drop to a point mostconvenient for the attendant. The diameters of the drum must beregulated according to height of and distance between. poles or endpoints. That part of the cables dealing out when the lamp is loweredhaving to deal out five or many times more than other parts are to takein the difference in diameters is made a ne cessity.

Owing to the fact that the cables are doubling up while the lamp isbeing lowered, it requires but little manual power to lift the sameagain into position, and all the parts'can be built substantial, safe,and durable.

Yoke G is pendent from chains g, the upper end of which is attached tocarriage E by means of a link, 6, and its object is to keep the cablesout of the way of traffic when. lamp is lowered.

In the frame-work of the basket blocks or cross-bars l[ are joined bystraps of iron, I, forming an oblong square, in the corners of which theuprights l) are inserted. Additional blocks, J and K, are bolted to I11,and in block K the recess 1) provides a seat for the lamp-board M.'lhumb-screws firmly hold down this board. If circular or in any othershape, recess L must be shaped accordingly in order to receive suchboard. A current is effected by suspending the wires along the cables onthe section extending from pulleys 9 to points 0 c by means of cords andrings in. same manner and principle of a sliding curtain, wires foldingup when lamp is lowered, and. stretch out again when raised, which isnot shown in the drawings.

I claim as my invention and desire to secure by Letters Patent- In adevice for suspending electric-light lamps, a series of cables, incombination with baskets C, carriage E, pulleys l, 2, 3, 4, 5, G, 7, 8,and .1, yokes .3 and G, and Windlass A, provided with a single drumdivided into parts of which. some are, in diameter, many times largerthan others, substantially and identically as shown, described, and forpurposes set lorth.

AUGUST SIEGRIST.
